While constructing DAC we always get a profile ie. metal travel distance to amplitude as a non linear curve. Less metal travel distance gives more equivalent amplitude. Now i got a doubt, in some occations we come across this curve as beam profile diagram apperas like gaussian beam.
can we use such DAC'S? some times i found it while working with TR Probes also.
For highly attenuating materials, the performance of the system is critical. The ultrasonic sensors,
the scanning area and the system settings should be flexibly adapted to the test task and the material.
These high expectations are met with the new and modular testing system SONOAIR. With the world’s first air-coupled phased-array UT inspection system SONOAIR we developed a technology that works with up to 4 transmitter and receiver channels with freely configurable square wave burst transmitters as wells as low noise receiving amplifiers.
